Hi again,
the coherent_ht.c changes are all to LYH's hardcodes to coherent_ht_finalize(). These are there to setup link speed and width on the cht nodes.
I remember tomz from LNXI was working on that on a higher level at pci setup. Is that code complete by now? Are all bridges set up full speed?
Then we could just drop this code, which i would favour. Otherwise it should walk into the motherboard specific code.
As far as I can see this code is noop anyways since speed changes need a reset or LDTSTOP_L which is not asserted here. LYH, any comments?
